LOOK FOR WEAVING SHORT WEFT FABRICS.

Specification of Letters Patent.

Application filed January 26, 1908. Serial No. 412,588.

To all whom 'it may concern:

Be it known that I, JULIUs GARs'r, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts have invented a new and useful Loom for Weaving Short-WeftFabrics, of WhlCh the following is a specification.-

This invention relates to looms, and while capable of use for severalvarieties thereof, it is particularly adapted to be applied to thatclass of looms which are employed for weaving fabrics from separateshort weft lengths to produce straw-matting, grass and reed carpets, andthe like. In this class of looms the shed is ordinarily set to be widerat the place where the weft threads or strands are to be introduced thanthefabric. In order to accomplish this, the reeds or reed-dents haveheretofore been made movable alon the lay so that they may be broughttoward each other as the lay beats up.

The principal objects of the present invention are to provideimprovements in the mounting an operation of the reed dents whereby saiddents will be caused positively to move uniformly towards each otherduring the beating up of the lay. One feature of the invention,therefore, is the construction of mechanism whereby this result may beac complished in a sim 1e and efficient manner.

Another object o the invention is to provide an improved form of guardfor the reed dents whereby the same is simplified and cheapened as faras cost is concerned, and

whereby the reed-dents may be brought" closer together than wouldotherwise be the case. This is accomplished by stamping the guards outof sheet metal and folding them over so as to embrace the respectivereeddents and placing the' folded parts in staggered relatlon with eachother so that they will not interfere with the closing up of the reeddents.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had .to the accompanyin drawings, in which,

igure 1 is a sectional view taken transversely through the lay, of ashort weftweaving loom showin one way in which the invention may be app'ed' thereto. Fig. 2=is a horizontal sectiona view of the same partsabove the frame showing the latter in plan. Fig. 3 is a perspective viewshowing one of the reed-dents, its guard, and the way in which thefabric is woven. Fig. 4 is a face viewof a blank for making oneof theards. Fig. 5 is a side elevation of the guar made therefrom. Figs. 6and'7 are similar views of the other'form of guard, and Fig. 8 isa viewshowing how the weft strand is crimped up in the manufacture of thegoods.

The invention is illustrated as applied to a loom having the usualharnesses 10, heddles 1'1, breast-beam 12, warp-board 13, and lay 14,the latter having as usual a horizontal bar 15. The lay as usual isprovided with a series of reed-dents 16, but mstead of being caused tomove toward and from each other during the beatin of the laysimply bythe pull of the war t eads, means is provided according to t 'sinvention for positively moving the reed-dents so as to cause them allto move uniformly inde endently of any variation in the tension of t edifferent warp threads. This means consists of guides for thereed-dents, these guides in the present instance being shown as mountedon a stationary frame 20 having a part 21 above the bar 15 and a part 22below it.

rated from each other sufficiently to permit the reed-dents to slidebetween them, and constituting guides therefor. These guides are at aslight angle to each other, those in the center bein exactly transverseto the lay and gradua y converging toward each other on both sides ofthecenter, as indicated most clearlyin Fig. 2. The reed dents are held onthe lay at the top by fitting them against a shoulder 24 thereon andapplying a plate 25 to the front of their upper ends. This leaves arecess in the top of the lay for the upper ends of these dents and theyfit therein in such a way that they can slide therealong. The lowerparts of the reed dents pass through the horizontal bar 15 and they areheld up by a late 26 enterin a notch in each of the rec -dents. From't's it will be seen that the reed-dents, are moved positively toward eachother as the lay beats up, and conse uently there will be noirregularity in the istances which separate them when they engage thepreviously woven part of the fabric. This msures absolute uniformity inthe product and gives greatly im roved results.

has been the custom heretofore, the breast-beam is provided with a dog30 which engages a lever 31 on the breast-beam on each beat to o erate aseries of guards 32 to liberate the we t strand a from the notches 33 Ineach of these parts is a series of guide-bars 23 sepa-v the cross bar.close together into contact and virtually conwith which the reed dentsare provided. The

lever is operated through a guide bar 34 cutering notches 35 in theguards as will readily be understood. Each of these guards is referablymade of a piece of sheet metal iaving two side members 36 and across-bar 37 or 38. These can be stamped out in a very sim le manner andthen folded over as indicate in Figs. 5 and 7 to form a sheath in Theside pieces 36 are folded stitute one element in the complete guard,

.but the cross-bars are folded over so as to cross bars or sheathes wereall of the same height. This constitutes a very simple and inexpensiveway of making these guards, and is an important feature of theinvention.

Fig. 8 shows one of the weft strands as it is formed by thisconstruction. It has angular indentations 4O alternately arranged on oosite sides for receiving the warp threads. hese are formed when theweft strand is in a moist condition, and by the contraction of the sameonaccount of the movement of the reed-dents when all of them are incontact with the weft sufficient stock is gathered together to permitthis shape to be formed. While I have illustrated and described apreferred form of the invention, I am aware that many modifications maybe made therein by persons skilled in the art without deof a frame infixed position and having converging guides, and reed dents movablymounted on said lay and guided in said frame.

2. In a loom for making short weft fabric, the combination with the lay,of a frame in fixed position and having guides converging toward thewarp board, and reed dents movably mounted In said guides, whereby thereed dents are uniformly brought nearer together across the fabric asthe lay beats up.

3. A loom having a lay, reed dents mounted on the lay, and movablelongitudinally thereon, and meansfor positively and uniformly movingsaid reed dents on the lay, toward each other during the beat of the layto assist in crimping the weft.

4. A loom having a lay, transverse guides, v

dent guides consisting of bars fixed to said frame and transverselyplaced with respect to the lay, and movable reed dents mounted in saidguides.

6. In a loom the combination of a fixed frame having reed dent guideslocated transversely to the lay but at a slight angle to each other,reed dents in said guides, and a lay connected with said reed dents andhaving means for moving them along as the lay beats up, said reed dentsbeing movable longitudinally to the lay.

7. In a loom the combination with the lay having a passage therethroughand reed dents extending through said passage, of a stationary framehaving reed-dent guides above and below said passage for said reeddents.

8. In a loom the combination with the lay havin a horizontal barprovided with a assage tierethrough, and reed dents exten ing throughsaid passage, of a stationar frame having reed-dent guides above and beow said passage for said reed dents, said guides converging toward thewarp board, the reed dent being movable along the lay by said guide asthe lay beats.

9. In a'loom the combination with a lay, having a plate removably fixedat the top thereof an spaced from the rear surface of the lay, reeddents passing into said s ace and movable therein and extending tirougha horizontal part of the lay below, and reed dent guides engaging thetop and bottom of said reed dents.
